New Comment:
I'm currently working on a patch, and a side thing that is coming out of this is an additional
$context parameter for use with non streams, since internally PHP is creating a stream with no
context, this can help work around supplying direct addresses like locations thats gated by custom
protocols or HTTPS which would need peer verification or similar.
I expect this patch to only go in PHP 7.2 and onwards.

It seems like all the exif_* functions do not support streams, I'm gonna take a look at it

while the posted example will work, it requires a lot memory on php-side because you need to read
the whole file + you need additional space for the base64 encoded string.
so its far away from an efficient solution and will not work for big/huge images.

Closing it as it's actually already supported via
exif_read_data('data://image/jpeg;base64,'.base64_encode(file_get_contents('image.
jpg')))

Description:
------------
exif_read_data currently read exif metadata only from filepath.
In case the image is in memory (stream resource, binary string, etc...) the image
as to be written on disk before reading the exif data.
It would be awesome to be able to read from a stream resource.
